Due to the noise, environmental impact and the shortage of land of the onshore wind farm, the wind farm is shifting from onshore to offshore. The wind distribution is more uniform and the wind turbine can operate more efficiency in offshore environment. However, the environmental loads of the offshore wind turbine, such as the wave, current and ship collision, are increased. In order to improve the reliability of the offshore wind turbine, the foundation of the offshore wind turbine should be studied more carefully. The Vestas V112 3 MW offshore wind turbine is use as the example for the calculation of the environmental loads. Three kinds of offshore foundation, which are monopole, tripile and tetrapile, are studied in this research. A monopile with diameter of 5 meter, thickness of 0.025 m and depth of 13 m can support the Vestas V112 3MW offshore wind turbine. A tripile, with three small piles of diameter of 3 m、thickness of 0.02 m、depth of 9 m and distance of between the piles 7.5 meter, could also support the target wind turbine. A tetrapile, with four small piles which has the diameter of 3m, thickness of 0.015m、depth of 9 m and distance between piles 7.5 meter also meets the requirement to support the Vestas V112 3MW wind turbine. Monopile is the best choice, when considering the weight of the structure, the cost of connection between the foundation and the support structure of wind turbine, to achieve cost saving and meet the design strength of purpose. 蔡進發 2011 學位論文 ; thesis 129 zh-TW |

碩士 === 國立臺灣大學 === 工程科學及海洋工程學研究所 === 99 === The wind power is one of the most promising renewable energy in the world. Due to the noise, environmental impact and the shortage of land of the onshore wind farm, the wind farm is shifting from onshore to offshore.

The Vestas V112 3 MW offshore wind turbine is use as the example for the calculation of the environmental loads.
